Product development requires the work of lots of different people with different skills to deliver their best efforts. So it's natural we want to be the best at what we do. When those people work in silos and can't share ideas or communicate, products suffer. Creating 't-shaped' skill sets, with deep knowledge of your own field and insight into those around you, can help. Using examples from the NHS, where multidisciplinary team working is critical to patient outcomes and supported by a culture of lateral learning and knowledge sharing, Louise looks at the benefits of knowing a little about a lot for product outcomes, team working and your own career, and shares a few surprising outcomes from her own 't-shaped' approach to learning new skills.
